THRASHING -MACHINE.

SPECIFICATION forming part of Letterslatent No. 290,647, dated Deceniber 18, 1883. Application filed January 11, 1883. No model.)

To all 1072,0111, it may concern:

Be it known that I, G. FRANK DIESSINGER, a citizen of the United States, residing at Stockertown, in the county of Northampton and State of Pennsylvania, have invented certain new and useful Improvements in Thrashing-Machines, of which the following is a specification, reference being hadtherein to the accompanying drawings.

My invention relates to thrashing-machines; and it consists in the parts which will be hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 represents a perspective view of a thrashing-machine provided with my improvements. Fig. 2is a central longitudinal section through the concaves, thrashing-cylinder, frame, and reversible table. Fig. 3 is a side elevation .of the improved part of my machine, and Fig. 4. is a front elevation of the same. Fig. 5 is a perspective view of a concave plate provided with spikes extending through on either side, short spikes appearing on the top side and long ones underneath. Fig, 6. is a fragment of a plate having on one side a concave blank, and on thereve'rse side a spiked face. Fig. 7 is a side elevation ofa spike, its nut and connecting-bar being in cross -section. Fig. Sis a perspective view of a spike with fragment of shank. This view shows the form of the shank and its be'veled shoulder. Fig. 9 represents in perspective the loose recessed pulley, provided in'said recess with a pin on which a pawl is loosely pivoted. a perspective view of the inside of a cupshaped cap provided on its inner sides with a series of ribs adapted to engage the pawl 011 the loose pulley. Fig. 11 is the reverse side of the pulley and cap shown in' Figs. 9 and 10. This cap fits into the loose pulley. so that the pawl in said pulley may engage the ribs in the cap. Said cap is provided with a key through its shoulder, whereby it maybe fixed to the cylindershaft. WVhen thus united, power may be communicated through the pulley to the cylinder, when said pulley is revolved, so that its pawl shall engage the ribs in the cap. By revolving the pulley reversely, the pawl is disengaged from said cross-pieces,

cross-section of the thrashing-spike, showing Fig. 10 is 1 Fig. 2, against which the 'upper sides of the the sharp corners coming into contact with the head of a spear of wheat. V The arrow in this view indicates the direction in whichthe spike is moving.

The same letters indicate corresponding parts throughout the several views.

A represents one of the concave plates, having a blank side, A, and reverse spike side, A A are holes for screw-shanks by means of which it is secured to a vertically-adjustable plate, C.

B is also a concave plate, provided on one side with short spikes B and on the other with long spikes B. i

B are end openings similar to and for the same purpose as the openings A in plate A. G are side plates, having slots 0. D is the side casing, provided with studs D. Said studs are in the nature of aheaded screw, by means of which plates G-niay be adjusted vertically and secured at any desired height.

E are the legs supporting the machine. F are cylinder-heads. F are the cross-bars uniting cylinder-heads F and carrying spikes G.

G is the threaded shank of tooth'or spike G, and G the beveled shoulderthereof, which fits closely into the opening'in cross-bar F.

H are nuts securing the spikes by their threaded shanks to said cross-bars.

I is a dust-plate in the nature of an under jaw to the feed-mouth of the machine.

J are studs on the inner side of trough J, against which the under side of the dust-plat abuts. v s

' J are studs on the inner side of easing D,

dust-plate rests. Said dust-plate is removable at pleasure, whereby one is enabled to obtain access to the teeth or spikes.

J Fig. 2, are also studs on casing D. The dust-plate is inserted between studs J 2 and J and the feed-board.

K is a reversible table provided with hooks K, by means of which said table is secured to studs J 3 on lugs J projecting from the easing D. l

K is the removable supportingleg of the table.

L are the end projections of the cylinder- Shaft.

M is the loose pulley,provided with stud or pin M.

N is a pawl moving freely on said pin.

0 is a cap,which fits into the recess of pulley M.

O are cross-strips in cap 0. a

O is a shoulder on the outer side of said cap, and 0 is a threaded key working in a threaded opening in said cap. Said key is adapted to engage either end of the shaft L, and thereby secure the cap and pulley to the shaft.

Goncaves A B are screwed at their ends to the tops of the vertically adjustable side plates, G, by means of which the concaves and united teeth may be raised or lowered with said side plates for the purpose of rough or fine thrashing, as desired; but the machine, however, by reason of my reversible concaves provided with several lengths of spikes and blank, is susceptible of still nicer and finer adjustment. For tough thrashing, the long spikes on both concaves should be used; but for buckwheat or similar grain the concaves should be reversed, and the short spikes and blank side presented to the cylinder. As short and'few spikes as possible should be used, in order to avoid cutting or breaking the straw or grain.

I11 practice the thrashers are made with six wrought-iron beaters fitted nicely into two cylinder-heads, which are keyed permanently on a steel shaft. These heaters are very strong, and have square holes, into which the teeth are nicely fitted to prevent them from turning, and secured with nuts on the inside. The cylinder is sixteen inches in diameter, and very heavy. Host of the weight is on the outside, which makes it keep its motion regular, and not easily checked b'y'irregular feeding. The cylinder runs independently, no part of the machine being run from it, thus saving power and lessening friction and wear, and allowing it to get speed much quicker. The sides of the thrasher are of solid castiron, strong and durable, to which the legs are bolted, and cross-pieces fitted between, fastened with joint-bolts, thus making a frame that can always be kept stiff and solid by tightening up the bolts, and cannot get out of shape, as is the case where frames are of wood and niortised and tenoned together. The motion of the cylinder sucks in the dust away from the feeder, and carries it off with the straw at the rear end of the machine. Said draft or suction aids greatly to feed the cylinder, and also to relieve it of straw after it has passed through the machine by the strong blast produced by the bars, so that the cylinder is free from the straw winding around it.

The feed table is provided with hooks, where it hooks to the machine, which can be done in an instant, and it is so arranged that it can be put on to extend either right or left. All other parts are made to be used either on the right or left side, such as the cylinder-pulley, shaker-wheel, cone-pulley, crank, and the spout that carries out the grain.

Having thus described my invention and set forth its advantages, I clainr as new and desire to secure by Letters Patent- 1. In a thrashing-machine, a spike provid ed with grooved sides and a shank, and a beveled shoulder at the point of intersection of said shank and spike, whereby the spike is strengthened at the strained point, as set forth, in combination with the cross-bar F, substantially as described, and for the purposes set forth.

2. The combination of the cylinder F F and shaft L L with the loose pulley M and cap 0, the parts being adapted to permit the application of said cap, and pulley at either end of said shaft, substantially as described, and for the purposes set forth.

3. In a thrashing-n1achine,the casing D and J, provided with studs, as specified, in combination with the removable dust-plate I and the cylinder, substantially as set forth.

4. The reversible table K, hooks K and detachable leg K, in combination with the easing D and studs J substantially as set forth.

5. In a thrashing-machine, a spike provided with longitudinal parallel grooved sides and a shank, and a bevel-shoulder at the point of intersection of said shank and spike, substantially as described, and for the purposes set forth.

6. In athrashing-machine, athrashing-spike provided with a series of longitudinal ridges with sharp edges along its sides, formed by a series of longitudinal grooves in said sides, whereby the spike is serrated in cross-section, the sharp corners or edges of the serrations being placed forward in the line of movement with the spike, as shown, thus bringing said edges into contact with the grain, and the hulling thereof facilitated, substantially as described, and for the purposes set forth.

In testimony whereof I affix my signature in presence of two witnesses.

G. FRANK .WIES'SINGER.
